After deprotection, a diamine is obtained, which is selectively coupled to an isophthalic acid monoamide at the primary amino functionality. The latter is prepared from dimethyl aminoisophthalate by successive sulphonation, methylation and then mono-saponification. The acid obtained is coupled with an amine and after further saponification is available for the final amide coupling mentioned above.

Scheme C illustrates by way of example another alternative method of synthesising the compounds according to the invention. Starting from a Boc-protected amino acid, a Boc-protected aminoaldehyde is prepared by reduction to the alcohol and subsequent oxidation. This is coupled by reductive amination to an amino acid amide which is obtained from a Boc-protected amino acid.

Mono-saponification, coupling of the resulting acid with an amine and further saponification yield the acid required for the final amide coupling mentioned above.

As stated previously, the compounds of formula (I) may be converted into the salts thereof, and particularly, for pharmaceutical use, into the physiologically and pharmacologically acceptable salts thereof. These salts may be present on the one hand as physiologically and pharmacologically acceptable acid addition salts of the compounds of formula (I) with inorganic or organic acids.

The acid addition salts may be prepared for example using hydrochloric acid, hydrobromic acid, sulphuric acid, phosphoric acid, methanesulphonic acid, acetic acid, trifluoroacetic acid, fumaric acid, succinic acid, lactic.acid, citric acid, tartaric acid or maleic acid.
Moreover mixtures of the above-mentioned acids may be used. For preparing the 2o alkali and alkaline earth metal salts of the compound of formula (I) with acidically bound hydrogen it is preferable to use the alkali and alkaline earth metal hydroxides and hydrides, while the hydroxides and hydrides of the alkali metals, particularly of sodium and potassium, preferably sodium and potassium hydroxide, are particularly preferred.

The compounds of general formula (I) according to the invention and the corresponding pharmaceutically acceptable salts thereof are theoretically suitable for treating and/or preventatively treating all those conditions or diseases that are characterised by a pathological form of f3-amyloid-peptide, such as for example 11-3o amyloid-plaques, or that can be influenced by inhibiting R-secretase. For example the compounds according to the invention are particularly suitable for the prevention, treatment or for slowing down the progress of diseases such as Alzheimer's disease (AD) and other diseases associated with , die with abnormal processing of the Amyloid Precursor Protein (APP) or aggregation of Abeta peptide, as well as diseases that can be treated or prevented by inhibiting (3-secretase or cathepsin D.

Suitable pharmaceutical formulations for administering the compounds according to the invention are for example tablets, pellets, coated tablets, capsules, powders, suppositories, solutions, elixirs, active substance plasters, aerosols and suspensions.
About 0.1 to 1000 mg of one of the compounds according to the invention or of a mixture of several of these compounds are formulated on their own or together with pharmaceutically conventional excipients such as carriers, diluents, binders, ~:.~ , stabilisers, preservatives, dispersants etc. To form a dosage unit in a manner known to those skilled in the art.

A dosage unit (e.g. tablet) preferably contains between 2 and 250 mg, particularly preferably between 10 and 100 mg of the, compounds according to the invention.
Preferably the pharmaceutical formulations are administered 1, 2, 3 or 4 times, particularly preferably once or twice, most preferably once a day.

The dosage required to achieve the corresponding activity for treatment or prevention usually depends on the compound which is to be administered, the patient, the nature and gravity of the illness or condition and the method and frequency of administration and is for the patient's doctor to decide.

Expediently, the amount of the compounds according to the invention administered is in the range from 0.1 to 1000 mg/day, preferably 2 to 250 mg/day, particularly preferably 5 to 100 mg/day when administered orally. For this purpose, the compounds of formula (I) prepared according to the invention may be formulated, optionally with other active substances, together with one or more inert conventional carriers and/or diluents, e.g. with corn starch, lactose, glucose, microcrystalline cellulose, magnesium stearate, polyvinylpyrrolidone, citric acid, tartaric acid, water, water/ethanol, water/glycerol, water/sorbitol, water/polyethylene glycol, propylene glycol, cetylstearyl alcohol, carboxymethylcellulose or fatty substances such as hard fat or suitable mixtures thereof, to produce conventional galenic preparations such as tablets, pellets, coated tablets, capsules, powders, suppositories, solutions, elixirs, active substance plasters, aerosols and suspensions.

The compounds according to the invention may also be used in conjunction with other active substances, particularly for the treatment and/or prevention of the diseases and conditions mentioned above. Other active substances which are suitable for such combinations include, in particular, thosewhich potentiate the therapeutic effect of a compound according to the invention with respect to one of the indications mentioned and/or which allow the dosage of a compound according to the invention to be reduced. Therapeutic agents which are suitable for such a combination include, for example, beta-secretase inhibitors; gamma-secretase inhibitors; amyloid aggregation inhibitors such as e.g. Alzhemed; directly or indirectly acting neuroprotective substances; antioxidants such as e.g. Vitamin E or ginkgolides; anti-inflammatory substances such as e.g. Cox inhibitors, NSAIDs with additionally or solely AR
lowering properties; HMG-CoA reductase inhibitors (statins); acetylcholinesterase inhibitors such as donepezil, rivastigmine, tacrine, galantamine; NMDA receptor antagonists such as e.g. memantine; AMPA agonists; substances that modulate the concentration or release of neurotransmitters such as NS-2330; substances that induce the secretion of growth hormone such as ibutamoren mesylate and capromorelin; CB-1 receptor antagonists or inverse agonists; antibiotics such as minocycline or rifampicin;
PDE-IV and PDE-IX inhibitors, GABAA inverse agonists, nicotine agonists, histamine H3 antagonists, 5 HT-4 agonists or partial agonists, 5HT-6 antagonists, a2-adrenoreceptor antagonists, muscarinic Ml agonists, muscarinic M2 antagonists, metabotropic glutamate-receptor 5 positive modulators, as well as other substances that modulate receptors or enzymes in a manner such that the efficacy and/or safety of the compounds according to the invention is increased and/or unwanted side effects are reduced.

Preferred combinations are those comprising one or more of the compounds according to the invention with one or more,of the following substances selected from among Alzhemed, Vitamin E, ginkgolid-ps, ddnepezil, rivastigmine, tacrine, galantamine, memantine, NS-2330, ibutamoren mesylate, capromorelin, minocycline and/or rifampicin.

The compounds according to the invention, or the physiologically acceptable salts thereof, and the other active substances to be combined therewith, may be present together in one dosage unit, for example a tablet or capsule, or separately in two identical or different dosage units, for example as a so-called kit-of-parts.

The compounds according to the invention may also be used in conjunction with immunotherapies such as e.g. active immunisation with Abeta or parts thereof or passive immunisation with humanised anti-Abeta antibodies for the treatment of the above mentioned diseases and conditions.
~ , ~; .

The dosage for the combination partners mentioned above is usefully 1/5 of the lowest dose normally recommended up to 1/1 of the normally recommended dose.

Therefore, in another aspect, this invention relates to the use of a compound according to the invention or a physiologically acceptable salt of such a compound combined with at least one of the active substances described above as a combination partner, for preparing a pharmaceutical composition which is suitable for the treatment or prevention of diseases or conditions which can be affected by inhibiting R-secretase.

The use of the compound according to the invention, or a physiologically acceptable salt thereof, in combination with another active substance may take place simultaneously or at staggered times, but particularly within a short space of time. If they are administered simultaneously, the two active substances are given to the patient together; while if they are used at staggered times the two active substances are given to the patient within a period of less than or equal to 12 hours, but particularly less than or equal to 6 hours.

Consequently, in another aspect, this invention relates to a pharmaceutical composition which comprises a.com'pound according to the invention or a physiologically acceptable salt of such, a compound and at least one of the active substances described above as combination partners, optionally together with one or more inert carriers and/or diluents.

Thus, for example, a pharmaceutical composition according to the invention comprises a combination of a compound of formula (I) according to the invention or a physiologically acceptable salt of such a compound and at least one other of the above-mentioned active substances, optionally together with one or more inert carriers and/or diluents.

The compounds according to the invention inhibit the proteolysis of the APP
protein between the amino acids Met595 and Asp596 (the numbering relates to the APP695 isoform) or the proteolysis of other APP.isoforrn.s such as APP751 and APP770 or mutated APP at the corresponding site, which is also referred to as the P-secretase cutting site. The inhibition of R-secretase should therefore lead to a decreased production of the P-amyloid peptide (AR).

The activity of R-secretase may be investigated in assays based on different detection technologies. In the test set-up a catalytically active form of P-secretase is incubated with a potential substrate in a suitable buffer. The reduction in the substrate concentration or the increase in product concentration may be achieved using various technologies depending on the substrate used: HPLS-MS analysis, fluorescence assays, fluorescence-quenching assays, luminescence assays are a non-representative selection of the different possibilities. Assay systems in which the effectiveness of a compound can be derti'onstrdled are described e.g. In U.S.
Patents US 5.942.400 and US 5.744.346 and hereinafter. An alternative assay format comprises displacing a known P-secretase ligand with a test substance (US
2003/0125257).

The substrate used may be either the APP protein or parts thereof or any amino acid sequence that can be hydrolysed by the R-secretase. A selection of these sequences can be found e.g. In Tomasselli et al. 2003 in J. Neurochem 84: 1006. A
peptide sequence of this kind may be coupled to suitable dyes that provide indirect evidence of proteolysis.
The enzyme source used may be the complete R-secretase enzyme or mutants with a catalytic activity or only parts of the P-secretase which still contain the catalytically active domain. Various forms of P-secretase are known and available and may serve as an enzyme source in a corresponding'test.s6t-up. This includes the native enzyme and also the recombinant or synthetic en zyme. Human R-secretase is known by the name Beta Site APP Cleaving Enzyme (BACE), Asp2 and memapsin 2 and is described e.g. In U.S. Patent US 5.744.346 and in the patent applications WO
98/22597, WO 00/03819, WO 01/23533, and WO 00/17369, as well as in the scientific literature (Hussain et al., 1999, Mol. Cell. Neurosci. 14: 419-427; Vassar et.
Al., 1999, Science 286 : 735-741; Yan et al., 1999, Nature 402: 533-537; Sinha et. Al., 1999, Nature 40: 537-540; and Lin et. Al., 2000, PNAS USA 97 : 1456-1460). Synthetic forms of the enzyme have also been described (WO 98/22597 and WO 00/17369).
(3-Secretase may be extracted and purified from human brain tissue, for example, or produced recombinantly in mammalian cell cultures, insect cell cultures, yeasts or bacteria.

To calculate the IC50 value of a substance, different amounts of substance are incubated with the R-secretase in an assay. The IC50 value of a compound is defined as the substance concentration at which a 50% reduction in the detected signal is measured by comparison with the mixture without any test compound. Substances are evaluated as having an inhibiting effect on P-secretase if under these conditions their IC50 value is less than 50 pM, preferably less than 10 pM, particularly preferably less than 1 pM and most particularly preferably less than 100 nM.

An assay for detecting R-secretase activity may have the following appearance, in detail:
The ectodomain of BACE (amino acids 1-454) fused to the recognition sequence for an anti-Myc antibody and a poly-histidine is secreted overnight by HEK293/APP/BACEect. cells in OptiMEM (Invitrogen). A 10 NI aliquot of this cell culture supernatant serves as an enzyme source. The enzyme is stable over more than 3 months when stored at 4 C or -20 C in OptiMEM . The substrate used is a peptide with the amino acid sequence SEVNLDAEFK to which the Cy3 fluorophore (Amersham) is coupled N-terminally and the Cy5Q fluorophore (Amersham) is coupled C-terminally. The substrate is dissolved in DMSO in a concentration of 1 mg/mI
and used in the test in a concentration of 1 pM. In addition the test mixture contains 20 mM NaOAc, pH 4.4, and at most 1% DMSO. The test is carried out in a 96-well dish in an overall volume of 200 pl over 30 minutes at 30 C. The cleaving of the substrate is recorded kinetically in a fluorimeter (ex: 530 nm, em: 590 nm). The assay is started by the addition of the substrate.
As controls, mixtures with no enzyme or with no inhibitor are included on each dish.
The IC50 value for the test compound is calculated using standard software (e.g.
GraphPad Prism ) from the percentage inhibition of the substance at different test concentrations. The relative inhibition is calculated from the reduction in the signal intensity in the presence of the substance based on the signal intensity without the substance.

The compounds (1) - (78) mentioned in the Table hereinbefore have IC50 values of less than 30 NM, measured using the test described above.

The activity of the P-secretase may also be investigated in cellular systems.
As APP
is a substrate for R-secretase and AR is secreted by the cells after the processing of APP by R-secretase, cellular test systems for detecting R-secretase activity are based on detecting the amount of Ap formed over a defined period of time.
The selection of suitable cells comprises, but is not restricted to, human embryonic kidney fibroblasts 293 (HEK293), Chinese Hamster Ovary cells (CHO), human H4 neuroglioma cells, human U373 MG astrocytoma glioblastoma cells, neuroblastoma N2a cells in the mouse, which stably or transiently express APP or mutated forms of APP, such as e.g. the Swedish or London or Indiana Mutation. The transfection of the cells is carried out for example by cloning the cDNA of human APP into an expression vector such as e.g. PcDNA3 (Invitrogen) and adding it to the cells with a transfection reagent such as e.g. Lipofectamine (Invitrogen) according to the manufacturer's instructions.
The secretion of Ap may also be measured from cells without genetic modification using a suitably sensitive A(3 detection assay such as e.g. ELISA or HTRF.
Cells that may be used for this are, besides other cells, human IMR32 neuroblastoma cells, for 2o example.

The secretion of AR may also be investigated in cells obtained from the brains of embryos or the young of APP transgenic mice, such as e.g. In those obtained by Hsiao et al 1996 Science 274: 99-102, or from other organisms such as e.g.
guinea pigs or rats.
Substances are evaluated as having an inhibiting effect on R-secretase if under these conditions their IC50 value is less than 50 pM, preferably less than 10 pM, particularly preferably less than I pM and most particularly preferably less than 100 nM.

An example of the procedure for carrying out a cell assay is described below:

MG cells which stably express APP (isoform 751) are cultivated in a culture medium such as DMEM+glucose, sodium pyruvate, glutamine and 10% FCS at 37 C in a steam-saturated atmosphere containing 5% CO2. In order to investigate the (3-secretase inhibiting activity of substances, the cells are incubated with different concentrations of the compound between 50 pM and 50 pM for 12-24 h. The substance is dissolved in DMSO and is diluted for the assay in culture medium so that the DMSO concentration does not exceed 0.5%. The production of AP during this period is detected using an ELISA, which uses the antibodies 6E10 (Senentek) and SGY3160 (C. Eckman, Mayo Clinic, Jacksonville, Florida, USA) as capturing antibodies that are bound to the microtitre plate and AR40- and AR42-specific antibodies (Nanotools, Germany), coupled to alkaline phosphatase, as detecting antibodies. Non-specific binding of proteins.to the microtitre plate is prevented by blocking with Block Ace (Serotec) before the addition of the AR-containing culture supernatant. The quantifying of the amounts of Ap contained in the cell supernatant is carried out by adding the substrate for alkaline phosphatase CSPD/Sapphire II
(Applied Biosystems) according to the manufacturer's instructions. Possible non-specific effects of the test compound on the vitality of the cells are excluded by determining precisely these effects by AlamarBlue (resazurin) reduction over a period of 60 minutes.
The potency of non-toxic substances is determined by calculating the concentration that brings about a 50% reduction in the amount of Ap secreted compared with untreated cells.

Moreover, different animal models may be used to investigate the P-secretase activity and/or the APP processing and the release of Ap. Thus, for example, transgenic r.4 ... ' animals that express APP and/or 0-sbcr-etase may be used to test the inhibitory activity of compounds of this invention. Corresponding transgenic animals are described for example in US Patents US 5,877,399, US 5,612,486, US 5,387,742, US
5,720,936, US 5,850,003, US 5,877,015 and US 5,811,633, and in Games et al., 1995, Nature 373: 523. Preferably, animal models are used that display some of the characteristics of AD pathology. The administering of (3-secretase inhibitors according to this invention and the subsequent investigation of the pathology of the animals constitutes a further alternative method of demonstrating R-secretase inhibition using the compounds. The compounds are administered in such a way that they can reach their intended site of activity in a pharmaceutically effective form and quantity.

The test for detecting cathepsin D (EC: 3.4.23.5) inhibition was carried out as follows:
20 mU of recombinant cathepsin D (Calbiochem, Cat.No. 219401) in 20 mM sodium acetate puffer pH 4.5 with 5 pM substrate peptide and different concentrations of the test substance are incubated at 37 C in a 96-well dish and the conversion is recorded for 60 minutes in a fluorimeter (emission: 535 nm, extinction: 340 nm). The peptide substrate used has the following sequence: NH2-Arg-Glu(Edans)-Glu-Val-Asn-Leu-Asp-Ala-Glu-phe-Lys(Dabcyl)-Arg-COOH (Bachem). However, a peptide or protein substrate with a sequence that can be cleaved proteolytically from Cathepsin D
may also be used. The test substances are dissolved in DMSO and are used in the assay after dilution to a maximum of 1% DMSO.
The assay is started by the addition of the substrate.
As controls, mixtures with no enzyme or with no inhibitor are included on each dish.
The IC50 value for the test compound is calculated using standard software (e.g.
GraphPad Prism ) from the percentage inhibition of the substance at different test concentrations. The relative inhibition is calculated from the reduction in the signal intensity in the presence of the substance based on the signal intensity without the substance.
The compounds (1) - (78) mentioned in the Table hereinbefore exhibited an inhibitory effect on cathepsin D in the test described here.
